Customer Ratings & Reviews

The headphones stay on during my workout but despite turning up the volume on my phone, the headphones is still not as loud as I expected compared to my old Sony headphones. Other than that, I am satisfied with my purchase.

I tried this pair of buds after using the Beats ( too delicate for sport ), the Adidas Senheiser over the hear ( weak sound ), and these are perfect. Easy to lock into your ears, good noise cancelling and great sound.

Work great! Easy to adjust and cut all outside sound out. Only thing that could be better is having a volume controller on the cord.

I use these about 4 times a week when working out. So far, they work as good as the day I got them despite sweat and strain on the cables.

I replaced a bluetooth headset for my treadmill workouts. The bluetooth headset kept coming out of my ears when I would sweat, so the convenience of a wireless headset was offset. These Sennheisers stay put, so I find myself less focused on keeping the earbuds in place than before. The comfort level is ok, nothing to write home about. I will likely look to in a different direction when it comes to replacing.

Overall good workout headphones. They stay in your ears, and quality seems good. A bit disappointed in sound quality given name and cost – but it's acceptable.

Until I tried this product I never had a earphone that functioned for biking. This set fits under the bike helmet straps and stays in the ear.

I needed headphones that don't fall out while I'm working out. These headphones definitely worked for me and provide great sound quality

they don't stick in my ear well despite the little grips they have and the rubber pieces of the earbud, fall off all the time. the sound is way better than a cheapy pair of those gummies for 9.99. I like this purchase, but i don't think it was worth the amount that they cost. i usually have to buy a new pair of earbuds twice a year and so far these ones haven't had loose cord or loose sound in one ear. it's been a few weeks.

Sound quality is amazing. I use it when I travel for my job. they work great on the airplane and are super comfortable.

Got these headphones on sale which made it even a better bargain. Soundis excellent and comparible to the set of Beats that I already had. Highly recommemded purchase.

I always had problems with earphones. I couldn't find one that it will not fall off my ear while working out. This stays all the time and I can concentrate in what I'm doing rather than in the earphone. I love it.

This is my second pair I use one for music when I walk I use one for my piano keyboard They always stay in place with the extra hook These are the best I've found

Sennheiser brings its quality audio reproduction and construction to a partnership with Adidas' excellence with sports performance. The Sennheiser - CX 685 will keep you going though the most intense workouts without worrying about the headphones slipping out of place from your ears. The design is genius as it features an appendage or "hook" that anchors inside the ear and provides an added support and fit to withstand your most intense workouts in the treadmill, elyptical, cycling, zumba, or whatever you do. Cable is long enough and a shirt clip of provided. I only rated the product with 4-stars on the comfort category as it initially might take a little time to get used to the fit. Overall excellent product from Sennheiser and Adidas.

I purchased this as a Christmas gift for my son and he loved them. He liked how snugly they fit in his ears.

I wanted a pair of in-ear headphones with good sound that DIDN'T have an inline Mic or Volume control. These worked out great. They are not fancy, but have a solid build and stay in the ear after running for a while. I sweat a lot so this was important to me. They have an adjustable stabilizer that holds on to the fold of your ear and that helps keep them in. Great sound, not too much Bass but has a decent kick to them, and isolates noise enough to stay focused.

Overall these seem like pretty good headphones but I can't get them to stay in my ears properly. If I push the headphone forward they are great and the bass comes through but that only last for a minute until the earpiece works it's way back out. I have a set of Bose that stay put but the rubber tips on those detach from the ear piece easily. I'll keep searching....

Really good headphones. Sound quality could be a little better but I'm probably being too critical. Only downside is I use these for running and after about 45min they get a little uncomfortable.

Have enjoyed these headphones the stay in my ear with activity like exercising or doing yard work.

Liked the sound the headphones provided but could only get them to fit into 1 ear well.
